System Application

5.1 Incorporation with the Master Design Simulator Figure 1 diagrammatically illustrates the interaction between the various sub-systems that go to make up the total Master Design Simulator. As a total system, all sub-systems will be scheduled as needed by the controlling program. The data require¬ments for each will be made available either by providing common storage in core or by outputting data to external storage devices such as magnetic tape, disk, drum, etc. The incorporation of the Geology and Reserves sub-system into the total system involves the establishment of an interface through which data may be readily dissemminated in either direction. This interface will be provided by a geological data library in which all information available from the sub-system is stored and can be readily accessed by the main program and/or other sub-systems. In Figure 7, the information flow between the Geology and Reserves sub¬system and other sub-systems is shown. 5.2 Independent Function Geology and Reserves sub-system is capable of functioning as an independent unit or in direct communication with another sub¬system. This is possible by either continued use of the data library or by redirecting output to other peripheral devices separate from the total system libraries. (Figure 8).
